Answer: D

Explanation:

Correct Answer. D. Command Prompt using the powercfg -requests command The powercfg -requests command displays which applications and drivers are preventing the system from going into sleep mode. This tool is useful for diagnosing power management issues following updates.

Option A is incorrect because Device Manager does not provide information on what prevents sleep mode Option B is incorrect although the Power troubleshooter can help resolve some power issues, it does not specifically list active power requests Option C is incorrect because while Event Viewer logs system events, it does not specifically list which processes prevent sleep mode
